The isolation of cellulose nanocrystals (CNCs) by organic acid hydrolysis can contribute to reducing the extensive use of mineral acids, but aspects related to performance, cost effectiveness, and sustainability still need to be addressed. Here, techno-economic analysis (TEA) and life cycle assessment (LCA) were performed to evaluate the production of CNCs using organic and/or inorganic acid hydro ...
